6 : 15 : 20

3 : 8 : 10

- Initially, the ratio a : b is given as 2 : 5.

- The ratio b : c is given as 3 : 4.

- To find a common ratio, make the 'b' values the same in both ratios.

- Convert the first ratio (a : b = 2 : 5) by multiplying by 3, resulting in 6 : 15.

- Convert the second ratio (b : c = 3 : 4) by multiplying by 5, resulting in 15 : 20.

- The combined ratio a : b : c is 6 : 15 : 20.

- Option 1 (6 : 16 : 21), Option 2 (2 : 5 : 7), and Option 4 (3 : 8 : 10) don’t match.

Option 3, 6 : 15 : 20 is correct.
